Dense water formation in the Greenland Sea between 1999 and 2009
(Master thesis, 2019-08-22)A 10-year continuous hydrographic data record from moored profilers located in the central Greenland Sea between 1999 and 2009 were used to examine the mixed-layer depth evolution through winter as well as interannual ... -
Density regulation in Northeast Atlantic fish populations: Density dependence is stronger in recruitment than in somatic growth
(Peer reviewed; Journal article, 2018-05)Population regulation is a central concept in ecology, yet in many cases its presence and the underlying mechanisms are difficult to demonstrate. The current paradigm maintains that marine fish populations are predominantly ... -
Density-dependent consequences of size-selective induced life-history changes to population fitness in medaka (Oryzias latipes)
(Journal article; Peer reviewed, 2020)There is an increasing concern about the potential for size-selective harvest to impair population persistence. Yet little is known about the relative contribution of the evolutionary (shifts in life history) and demographic ... -
Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
(Journal article; Peer reviewed, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
The Departure from Mixed-Layer Similarity During the Afternoon Decay of Turbulence in the Free-Convective Boundary Layer: Results from Large-Eddy Simulations
(Journal article; Peer reviewed, 2023)This study analyses the departure of the velocity-variances profiles from their quasi-steady state described by the mixed-layer similarity, using large-eddy simulations with different prescribed shapes and time scales of ... -
The Dependence of Cold and Hot Patches on Local Plasma Transport and Particle Precipitation in Northern Hemisphere Winter
(Journal article; Peer reviewed, 2022)By using a database of 4,634 cold patches (high density and low electron temperature) and 4,700 hot patches (high density and high electron temperature) from Defense Meteorological Satellite Program F16 in 2005–2018 winter ... -
Dependence of Sudden Stratospheric Warmings on Internal and External Drivers
(Journal article; Peer reviewed, 2020)A sudden stratospheric warming (SSW) is a large-scale disturbance of the wintertime stratosphere, which occurs especially in the Northern Hemisphere. Earlier studies have shown that SSW occurrence depends on atmospheric ... -
Dependence of the global dayside reconnection rate on interplanetary magnetic field By and the earth’s dipole tilt
(Journal article; Peer reviewed, 2022)In the recent years, significant attention has been given to the combined effect of Interplanetary Magnetic Field (IMF) duskward component (By) and dipole tilt on the global magnetosphere-ionosphere system response. Numerous ... -
Dependencies: No Software is an Island
(Master thesis, 2013-10-15)In the past years, package managers, application frameworks and open-source libraries have made it vastly simpler and faster to get functioning software up and running, while cloud providers and external service providers ... -
Depletion of the human N-terminal acetyltransferase hNaa30 disrupts Golgi integrity and ARFRP1 localization
(Peer reviewed; Journal article, 2017-04-28)The organization of the Golgi apparatus (GA) is tightly regulated. Golgi stack scattering is observed in cellular processes such as apoptosis and mitosis, and has also been associated with disruption of cellular lipid ... -
Depositional and structural relationships along the basement-Cambrian contact in the Hardangervidda area
(Master thesis, 2016-06-01)The Scandinavian sub-Cambrian peneplain is an important reference surface used in reconstructing the geological evolution from the Neoproterozoic to the present. A detailed study of the geomorphological and structural ... -

Depth‐dependent permeability and heat output at basalt‐hosted hydrothermal systems across mid‐ocean ridge spreading rates
(Journal article; Peer reviewed, 2018)The permeability of the oceanic crust exerts a primary influence on the vigor of hydrothermal circulation at mid‐ocean ridges, but it is a difficult to measure parameter that varies with time, space, and geological setting. ... -
Derivation and numerical solution of fully nonlinear and fully dispersive water wave model equations
(Doctoral thesis, 2017-06-09)The water wave theory is a classical part of Fluid Mechanics. It has a long scientific history with a great number of mathematical results [10, 32]. The first studies in this field were done by Stokes in 1847 [34]. He ... -
Derivation of Boussinesq's shoaling law using a coupled BBM system
(Peer reviewed; Journal article, 2013-03-14)This paper is focused on finding rules for waveheight change in a solitary wave as it runs up a slowly increasing bottom. A coupled BBM system is used to describe the solitary waves. Expressions for energy density and ... -
Derived equivalences of canonical covers of hyperelliptic and Enriques surfaces in positive characteristic
(Peer reviewed; Journal article, 2019)We prove that any Fourier–Mukai partner of an abelian surface over an algebraically closed field of positive characteristic is isomorphic to a moduli space of Gieseker-stable sheaves. We apply this fact to show that the ... -

Description and evaluation of the Bergen climate model: ARPEGE coupled with MICOM
(Peer reviewed; Journal article, 2003-07)A new coupled atmosphere–ocean–sea ice model has been developed, named the Bergen Climate Model (BCM). It consists of the atmospheric model ARPEGE/IFS, together with a global version of the ocean model MICOM including a ... -

Design and Development of Game-based Oculomotor Training using Eye Tracking
(Master thesis, 2018-08-21)Many people have oculomotor issues. This means that they have a problem with how their eyes behave, or more importantly how they behave together. These issues are present both in children and adults and could lead to the ...
